The quotient of two numbers is the result of the division of the first listed number by the second listed number.

Also, the product of two numbers is the result of the multiplication of the first listed number and the second listed number.
But because, multiplication operation is comutative [the result is the same irrespective of which is listed first].
We can say that the product of two numbers is the result of the multiplication of the two numbers irrespective of which is listed first.

Given the expression
$\frac{x-2}{x^2+9}$
Here, x - 2 is being divided by $x^2+9$ .

Therefore, the accurate descripton of the given experession is the quotient [becuase of division] of x - 2 [the numerator or the dividend] and $x^2+9$ [the denominator or the divisor]
(option A).

Answer:

1 1/6 - 7 3/6 = -19/

= -6 1/

≅ -6.3333333

Step-by-step explanation:

Conversion a mixed number 1 1/

to a improper fraction: 1 1/6 = 1 1/

= 1 · 6 + 1/

= 6 + 1/

= 7/

To find new numerator:

a) Multiply the whole number 1 by the denominator 6. Whole number 1 equally 1 * 6/

= 6/

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7

c) Write a previous answer (new numerator 7) over the denominator 6.

One and one sixth is seven sixths

Conversion a mixed number 7 3/

to a improper fraction: 7 3/6 = 7 3/

= 7 · 6 + 3/

= 42 + 3/

= 45/

To find new numerator:

a) Multiply the whole number 7 by the denominator 6. Whole number 7 equally 7 * 6/

= 42/

b) Add the answer from previous step 42 to the numerator 3. New numerator is 42 + 3 = 45

c) Write a previous answer (new numerator 45) over the denominator 6.

Seven and three sixths is forty-five sixths

Subtract: 7/

- 45/

= 7 - 45/

= -38/

= 2 · -19/

2 · 3

= -19/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 6) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 6 = 36. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - seven sixths minus forty-five sixths = minus nineteen thirds.
